I created this PVC furler support to aid in keeping the CDI furler from bending while the mast is down. I took a 5 ft piece of 3" PVC SCH 40 pipe and split it lengthwise. I then opposed the two pieces so they could be bolted together at the half-way point with 1/4" 20 X 1" SS machine screws and fender washers.
I then routed out the area where the halyard keepers are located using a 5/8" drill bit so I could use them to connect a bungee cord and secure the support to the mast. This allows the furler drum to extend just beyond the end of the support eliminating the bend caused by the drum being inside the support. Total price to protect an expensive piece of equipment: $19.00
